Standard Smoke Curtain incorporating fiberglass fabric.

DSI-HS10B Hose Stream Rated Smoke and Fire Curtain

The DSI-HS10B Hose Stream Rated Smoke and Fire Curtain incorporates the cutting-edge technology of our UL 10D curtain products but with the advantage of being code compliant in any fire wall rated up to 3 hours.

With a UL10B 3-hour fire rating, the DSI-HS10B Fire Curtain can be used in fire walls and fire barrier walls as a replacement solution to traditional Coiling Steel Fire doors.

The assembly is comprised of a proprietary multi layered fire rated fiberglass/stainless steel fabric wound around a roller which is encased in a compact head box that is typically installed above the ceiling with side guides that are buried in the wall. This makes the system virtually invisible until activated.

Advantages vs Coiling Steel Fire Doors:

  • Cost effective
  • Lightweight – 75% lighter than overhead steel fire doors
  • Compact headbox – as little as 9” but no more than 12” of headroom required for larger sizes
  • Minimal side room required — 4” for any size
  • No size restrictions – Almost unlimited in size
  • Various egress options available
  • 24-volt system with Battery backup standard
  • Gravity Failsafe System with Auto reset
  • No exposed mechanisms, gears, chains, or motor parts
  • Can be almost completely hidden in your architectural design scheme
  • Code Compliant – Tested and Labeled to UL 10B 180 minutes with hose stream. UL1784 “S” label
